Etymology
The word 'recirculation' is built upon the core Latin noun 'circulus', meaning a small ring or circle, which itself is a diminutive of 'circus', denoting a circular line or course. The prefix 're-', meaning "again," was attached to the verb 'circulate' (to move in a circle) to form 'recirculate', signifying the action of causing something to move in a circle once more. Finally, the noun-forming suffix '-ation' was added to denote the process or result of this repeated circular motion. Thus, the term logically evolves from the literal concept of "making something go around in a circle again" to the modern technical meaning of a process where a substance or signal is repeatedly cycled through a system.
